Abstract: A pyrolytically cleaned oven includes an upper broil element and a lower bake element, the broil element is energized until the oven temperature reaches a trigger temperature, well below the glass transition temperature point of the oven porcelain enamel; then the bake and broil elements are alternately energized in a cyclical manner until an off temperature, somewhat above the trigger temperature but still below the transition temperature, is reached. Thereafter one or both of the elements are cycled to maintain the temperature with a range between the off temperature and a lower on temperature, also within the effective self cleaning range.
